Bitcoin ETFs see first outflow in 10 days as $149 million exits

US spot bitcoin exchange-traded funds recorded their first net outflow in 10 trading days on Wednesday, September 30. Investors pulled a combined $148.7 million from the funds, ending a nine-day run that had drawn in $3.1 billion.

The figures come from The Block, which counts daily creations and redemptions across the US funds. A separate tally from the outlet Bloomingbit put the day's net outflow at $148.69 million, nearly the same number. The run that broke had, only last week, turned 2026 flows positive after a weak start to the year.

Where the money left

Almost all of the selling sat in one place. Fidelity's FBTC shed $125.6 million, the bulk of the day's total. BlackRock's IBIT, the largest of the funds, lost $9.5 million. Bitwise's BITB gave up $13.6 million. The rest barely moved.

Ether funds leaned the same way. The nine US spot ether (ETH) products saw $59.6 million leave on the day, and Fidelity's FETH accounted for $26.6 million of that. Both sides finished red.

One day, not a trend

A single session does not undo a month. September brought $2.65 billion into the bitcoin funds. Set against the more than $100 billion the spot bitcoin ETFs now hold, Wednesday's outflow is a rounding error, about one part in 700. A pause, not a turn.

Context sits in the streak that just ended. Over the previous nine trading days, the bitcoin funds took in $3.1 billion, a steady bid that ran through late September. Wednesday broke the rhythm. It did not reverse it.

Year to date, the picture is still green, if barely. Trackers put 2026 net inflows between about $930 million and $970 million, depending on the provider. Since the first US funds opened in January 2024, they have taken in more than $57 billion, according to The Block.

Daily flows swing for dull reasons: one big holder rebalancing, a hedge being unwound, quarter-end bookkeeping. The data does not say who sold or why, and issuers rarely comment on one day's moves. One day is noise. Reading a single red print as a verdict tends to mislead.

Yields and a stalled price

The wider backdrop is a bond market pulling against risk. The US 10-year Treasury yield sat near 5.29% at the end of September, its highest since May 2002, according to market site UseTheBitcoin. Higher yields on safe government debt raise the bar for holding an asset that pays no income.

Bitcoin itself drifted. It traded at $83,448.09 at 13:30 UTC on October 1, down after failing to hold above $85,000 earlier in the week, according to Fortune. Ether changed hands at $2,688.17 at the same moment. The pullback left it near the lower end of its recent range.

What to watch

One outflow does not set a direction. What counts is whether the next sessions follow it, or whether the money returns as fast as it left. The Federal Reserve's next rate decision, and the path of Treasury yields, will move the funds more than any single day's tape. For now, one red day stands against a month of green.
